Training to failure once a while is fine, but it is simply not possible to train at a high frequency and go to failure regularly. I personally do not prefer to train to failure more than once every two weeks per muscle group.
I advise people that are new to the gym (between 6 months to 2 years of training) to go to failure frequently so that they may accurately gauge what 1 RIR feels like.
Almost every serious lifter is familiar with RPE (rating of perceived exertion) and RIR (reps in reserve). If you reach failure on an exercise, you experience a greater amount of fatigue than if you stopped one rep shy of failure. This allows you to then train the same muscle sooner and you end up building more muscle overall (the muscle gain at RIR 1 & RIR 0 is negligible). But, you need to be able to accurately gauge RIR, which is quite difficult for new lifters.
I used Input Sans for some time as my coding font. Most proportional fonts have a small <space> which makes it difficult to figure out alignment in code. Input Sans was the only font I found that was good in this regard.
I use vim keybinds and movement was too unpredictable to keep using as my main font. Now I'm back to a monospaced font.
I used to make music so I purchased studio monitors and a mic. I haven't put on a headset in years and I can't imagine how it would feel to wear one for 8+ hours a day.
I'm also a vim user and I recently switched to Colemak-DH, but I didn't remap anything. It took a long time to get used to the new vim layout (longer than the time it took to learn Colemak itself), but now that I'm comfortable with it, I can be fluent without any remaps.
